The engineering at Ba is second to none. Managers of the business units and communications and finance are not an area where I can say I have personal experience. As for the product line, most are top performers and the market has proven that. The rudder problem could never be substantiated even through extensive testing. Since we could never duplicate the suspected problem it remains a sad chapter in that aircrats history. I will say here and always have, that BA never put an airplane in service where the flying public was at risk. And that carried over to flight testing where the envelope was always expanded. Anyone with a question or doubt about any testing, and that airplane sat on the ground until all were satisfied. Didn't matter if it were a pilot or engineer or support folks like myself. Sorry, have to take issue with your position.
